Pinout (6-pin SOT-23 Package):
Pin Number Pin Name Pin Function Pin 1 IN1A Input 1A (Analog Signal Input) Pin 2 IN1B Input 1B (Analog Signal Input) Pin 3 GND Ground (Connection to the circuit's ground) Pin 4 VCC Positive Supply Voltage ( Power input for the IC) Pin 5 OUT1 Output (Analog Signal Output) Pin 6 NC No Connection (Optional or unused)Detailed Function of Each Pin:
IN1A: This pin is used as one of the inputs for the analog switch. It is the first analog signal input, where the signal to be routed through the switch can be applied. IN1B: This is the second analog input pin. The switch connects either IN1A or IN1B to the output pin depending on the control signal. GND: This is the ground pin for the IC. It is essential for completing the electrical circuit and ensuring proper operation of the IC. VCC: The VCC pin provides the power supply for the IC. This should be connected to the positive power rail of the system (typically 3.3V or 5V). OUT1: This is the output pin where the selected signal (from IN1A or IN1B) is routed. The analog switch connects either IN1A or IN1B to OUT1 depending on the logic state applied to the control pins. NC: This pin is marked as "No Connection." This means it has no electrical connection and is unused in the operation of the component.Circuit Principle:
The TS5A23157DGSR is a single-pole, double-throw (SPDT) analog switch. It is designed to select between two input signals (IN1A and IN1B) and route them to the output pin (OUT1) depending on a control logic input. The switch uses MOSFET technology to achieve low on-resistance, making it suitable for high-speed signal switching.
When a control signal is applied to the switch, it determines whether the IN1A or IN1B input is connected to OUT1. The VCC pin powers the switch, and the GND pin ensures proper operation by grounding the circuit. The NC pin is an unused pin and does not affect the operation of the switch.Frequently Asked Questions (FAQ):
